Additional TX/RX queue pairs require dedicated interrupts. Extend
binding with additional interrupts.

No. The order of items must be fixed. Now you allow any combination,
which is exactly what we do not want.

Not really. Interrupts are fixed, unless explicitly mentioned otherwise.
+      "mac" is the main interrupt for basic MAC features and the first
+      TX/RX queue pair. If only a single interrupt is available, then
+      it is assumed that this interrupt is the "mac" interrupt.
+      "txrx-[1-7]" are the interrupts for additional TX/RX queue pairs.
+      These interrupt names shall start with index 1 and increment the
+      index by 1 with every further TX/RX queue pair.
Skip last three sentences - they will become redundant after
implementing proper items.
